Type EWD-H-C1 Elevator Load Weighing Device. elevator load sensor.

INTRODTION MANUAL

Attention: The system is suitable for elevator that adopts the Can_BUS agreement (rope installed load weighing device), please kindly read the following chapters before operation. The elevator load weighing device has strict payload limit, please suitably installed; our company will not responsible for any loss for person and the device caused by unsuitbale operation otherwise.

Note: We are only responsible for the quanlity of products itself in any cases.

Announcement: Our company reserve the right to change the products for the development of the technology, the parameters will be subject to random products manaul.

The appearance and installation instruction of the products

1. The sketch of the mechine appearance:picture[1]

2. The installation sketch of the movable car system: picture[2]

 Try to install the sensor at the center of the car or the original overload switch of the elevator, installing the sytem at the bottom beam of the supporting, getting the inductive magnet attracted on the moving car and make sure the observe side faces the induction point of the sensor.

‚The support of the system should be made according to the basis condition of the elevator, and adopt to the material which is not so easy to deformation. The thickness of the support should be more than 4mm or with reinforcement to avoid swinging.

ƒ Installing the system to let the magnet at the bottom of car face the center of the upper sensor. Make sure the end face of the sensor parallel with the end face of the magnet.

System debug and illustration:

1. System debugging operations:

The system debug under other situation:

If there should be the following situations, it needs some ammendment of the system, the method are illustrated as before.

1. The weight of the car changes due to decoration;

2. Mechanical deformation of the car;

3. The non-ignorable influence of the car damping rubber elasticity coefficient caused by the changing temperature;

4. The aging and deformation of the damping rubber;

5. The header and squat down bottom of the elevator;

6. The loose of the fixed sensor.

How to expand the testing position range?

The factory default is 0-9.9mm, if there should be special demand, please operate according to the following:
